The following are examples of j_profile.d.

This script samples on-CPU stack traces and prints them with Java
translations.  With DTrace, as well as tracing events, you can also sample
them.  Each approach has its own advantages and disadvantages and you are 
encouraged to try both when investigating performance issues (especially 
tracing).  Sampling is inaccurate and can miss events, yet is a quick and 
easy way to discover a certain set of performance issues involving on-CPU 
load.  
  
This script samples at 101 Hertz, printing out the 25 most frequently seen 
stack traces down to 10 lines deep. All of these values can be tweaked in 
the script.

Here we run the script on Code/Java/Func_loop.  The argument fed to the script
is the PID of the Java program we wish to investigate.  Here the raw output is
show, then again after filtering using c++filt.

The most frequent stacks had Func_loop.func_c() on CPU, with a stack trace
showing func_b() and func_a() - as expected from the source to Func_loop.java.


Now passing that output through c++filt to translate the compiled C++ symbols
of the JVM.
